概要
Description
PMEG4030ER-QX is an N-channel enhancement-mode power MOSFET from Nexperia’s PMEG family. It is designed as a compact, efficient switch for low- to moderate-voltage power electronics. The “30” in the name typically indicates a 30 V drain‑to‑source rating, and the “QX” suffix denotes a specific SMD package. Typical uses include switching regulators, DC‑DC converters, load switches, and motor drivers, where fast switching and low on‑resistance are advantageous. It is driven from a logic‑level gate in many applications, allowing direct MCU drive in suitable designs. For exact electrical specs (Vds, Id, Rds(on), gate threshold, switching times), package details, and thermal limits, consult the official datasheet for PMEG4030ER-QX. Always verify the precise values for your chosen lot and packaging.
